Piston Seal CP Profile

Piston Seal CP Profile

Piston Seal CP Profile


Description

The Parker CP profile is a cap seal with anti-extrusion, low friction and low wear features. The CP profile is a bi-directional piston seal for use in low to medium duty applications. The CP profile retrofits into a standard size O-ring groove without modification. There are three CP profiles to match the groove width for a single O-ring, O-ring with one back-up, or an O-ring with two back-up rings. Because of the unique design of the filled PTFE cap, the CP profile offers long wear, low friction and antiextrusion. Because of its short assembly length, only minimal gland space is needed to fit the seal on the piston. Parker’s CP profile will retrofit non-Parker seals of similar design.

The CP profile may be ordered without the energizer by omitting the energizer code. See part number nomenclature in the downloadable PDF.

Notched Side Walls

Adding an “N” to the end of the part number indicates that notches are to be added to the side walls of the PTFE cap. Notches can help optimize the seal’s response to fluid pressure. In application, the void created by the notch allows fluid pressure to fill the cavity between the side face of the gland and the seal. Consult your local Zatkoff Seals & Packings representative for the availability and cost to add side notches to the CP profile.
